STANDING VALVE.

Application led September 10, 1925. Serial Re. 55,618.

This invention relates to pumps and more 'particularly to deep lwell pumps.

In the ordinary type of pump used in oil wells there is provided a casing or well f 6 tubing extending from the earth to a point 15 ing barrel withV liquid upon each actuation of the pump rod and traveling valve. Any gas present in the working barrel when the traveling valve starts downwardly will be compressed and the traveling valve will not open. If the traveling valve fails to open and the oil from the working barrel does not pass through the traveling valve the column of oil in the well tubing descends with the valve. In deep wells, this column of oil may be five thousand feet or more-in length and the stopping of this downward inove-` ment when the traveling valve reaches the A bottom of its stroke causes a terrific force to be exerted on'the working barrel, which frequently causes the working barrel to burst.

A further objection tothe standard' type of'pump when gas is encountered is that`the gas compressed on the downward movement gf the traveling valve will expand when the valve moves upwardly and, while this expansion is taking place the standing valve at the bottom does not open and no additional oil isdrawn into the working barrel. object of the present invention is to rovide a valve arrangedabove the working barrel to take the weight of the column of oil oi the traveling valve and to prevent sand from returning to the working'barrel 435 andclog ing it.

-A.furt er Objectis to provide a valve on which a stuiling box may be mounted land through which the pump rod lmay be ex tended. e

In the accompanying drawing I- have of a well casing showing the working barrel, traveling valve, standing valve, and showing the valve forming the subject matter of the present invention.

Referring to the drawing .the reference numeral 1 designatesthe pump rod which extends downwardly from the top of the well casing and is connected to the traveling valve inthe usual manner. The pump rod is surrounded by 'a stuiiing box cap 2 within which is arranged a stuffing box gland 3. The stuiing. box packing 4 is larranged around the' pump rod beneath the gland.- A cylindrical member 5 is connected to the cap and forms a connection between the cap and the valve body. The valve body. consists of a tubular body portion 6 which is received within the vfcylindrical member 5 and extends for an appreciable distance around the pump rod. A sand apron 5a extends downwardly yfrom the member 5 and is slightly spacedrom the valve body 6. A conical skirt 6a is formed on \the bottom of the tubular valve member and this skirt bridges the space between the pump rod and the casing. As shown, the. skirt is provided with openings to permit the passage of oil. 4The valve consists of a tubular member 7 surrounding the tubular valve body and extending upwardly inside the apron 5a. The lower end of this tubiilar body is provided with a conical skirt 7b which seats upon the conical portion 6'* of the valve seat when the valve is in lowered position to close the openings in the valve seat. The ring or skirt -7b may be' provided with ribs 7a by means 'of which it is connected to the tubular portion 7. The valve member is received in a coupling 10 which is connected to thewell tubing 9 by screw threads and is connected to similar tubing 11 arranged beneathait. The interior ofthe valve is pro` vided with deecting wings 8 which produce a/whirling motion in the oil passing through theyalve thus lifting the valve member with a rotary motion and regrinding its seat. The tubing 11 is connected to a coupling 11* which in turn is 'connected to aworkingbar rel 12. A traveling valve 13' is arranged in the-working barrel and secured to the pump -rod. At the bottom of the working barrel I..

104 y is retained inlposition by a plug or -coul there is provided a standing valve 14. which pling 15. y Tlie operation ofthe device willbe apparent, fromvthe foregoing description. On

the upward movement of the pump rod the standing valve 14 is opened by suction drawing a quantity of oil from the well into the working barrel. When the pump rod moves downwardly the oil lifts the traveling valve' I 13 from its seat and passes upwardly into the well tubing 9. This upward movement of the oil also lifts the valve 7 from its seat to permit the oil to pass into the well tubing. If the working barrel is not completely filled with oil on the upward movement of the pump rod the valve 7, which is stationary, prevents the column ofoil in the well tubing from following the traveling valve as it moves downwardly and thus eliminates pounding. The construction of the valve 7 is such that sand is prevented from returning to the working barrel and clogging the traveling valve.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit 'of the invention or the scope of the subjoined claims.

I claim:

1. A valve for oil wells adapted to be arranged above the traveling valve comprising a tubular body throughA which the pumprod is adapted to pass, an outwardly extending ortion formed on the bottom of said tubu-,

ar body and extending to the inner wall of the well tubing, said extension being provided with openings fforming a valve seat, a valve arranged over said seat, said valve comprising a tubular portion surrounding said tubular body and`an outwardly extending portion adapted to close said openings when'the -valve is seated, a stui'ling boX arranged on said tubular body above said valve member, and a sand apron surrounding the upper end of the tubular portion of said valve member.

2. A valve -for oil wells adapted to be arranged above the traveling valve comprising a tubular body through which the pump rod is adapted to pass, an outwardly extending portion formed on' the bottom of said tubular body and extending to the inner wall of the well tubing, vsaid extension being provided with openings and forming a valve l seat, a valve arranged over said seat, said valve comprising a tubular portion surrounding said body and an outwardly eX- tending portion adapted to close said openings when the valve is seated, packing surrounding the pump rod adjacent the upper end of said 'tubular body, a packing gland arranged above said packing, a cylindrical member arranged over said packing and connected toV said tubular bo'dy, a bearing cap secured to said tubular member, and a depending sand apron carried by said cylindrical member and adapted to surround the upper end of the tubular portion of said valve member.
